INTERIOR-WALL GONSTRUCTION.

My invention relates to new and useful im provements in interionwalls and ceilings and more particularly-to the plaster slabs out of whichthe walls and ceilings may be constructed. p

Still another object of the invention is to so cut the slabs that the hand of the artisan may be inserted therein for fastening the slabs in their proper places. p

' Still another object of the invention isto forinthese plaster slabs with a plurality of cut away portions at'certain specified points, so that not only may the hand of the plasterer be placed through the openings to attach the slabs to the desired places, but furthermore,

Wood blocks may be placed in the lower or upper respective openings, so that the picture moulding or base board may be nailed to these blocks, thus securing the baseboard or picture molding in place without in any way damaging the plaster slabs' Still another objectof the invention is to construct an interior wall or ceiling out of a plurality of like plaster slabs and so arrange 3 the reinforcing flanges inthe slabs that the openings in the flanges will register and thus provide a circulating air space between the ceiling slabs and floor to which it is hung,

in the summer and likewise warmer in the winter; 1

Still another object of the invention is to provide these slabs with a plurality of cut out portions'at respective points, so that the slabs may be easily and conveniently held by the artisans in assembling the wall or in moving the slabs from one piace'to another.

The present invention is also in the form of a companion application to the application filed by me on the 24th day of September, 1926, and bearing Serial Number 137,460. v

Still another object of the invention is to so provide the slabs that one series may be placed in an upright position, while an adjacent series may be placed in a horizontal position, the backs being face to face to form aspace between the two series, which may or embedded within the edge may not be filled with plaster, cement or other material.

till another object of the invention is to so construct the slabs that they may be easily supported to form ahanging ceiling, as will be more particularly pointed out in the specification.

Referring now to the drawings:

Fig. l isa perspective view of a partition wail embodying the invention.

Fig. 2 is a vertical sectional view showing one form of the slabs attached to a brick or concrete wall.

Fig. 3 is a fragmentary transverse section of a concrete floor showing 110w the slabs may; be attached as a ceiling.

Fig. 4 is a sectional view illustrating the method of holding the nuts in proper placement for the attaching means during the hardening of the concrete.

Fig. 5 is a perspective of one form of a vertical slab.

Fig. 6 is a similar view of a horizontal slab of-the other form.

Fig. 7 is a fragmentary perspective View of a ceiling showing the slabs attached tothe under side of a wood floor construction.

Fig. 8 is a fragmentaryperspective view showing how the slabs are attached to a sli htly diil erent wooden construction.

Referring now more specifically to the several views and for the moment to Fig. 5, there is shown a plaster slab l, in which there is preferably embedded a layer of burlap 2, while reinforcing rods 3 may also be embed ded in the plaster slab to strengthen the same if so desired. I

urthermore, there may be seen the sheet-v metal angles at and 5 and each have a flange of the slab. Each of these angle members are provided with a series of staggered openings 6, and although I have not shown them extending throughout the length of these members, it will be understood that they do, as they provide passages for the circulation of air in some instances, and also permit tying means to be passed through them in some instances for supporting the slabs in place, as will be hereafter mentioned.

So far as described, this slab is similar to the slab set forth in my co-pending application, the serial number of which is above noted, with the exception that the openings in the angles of this new slab are shown as rectangular in shape and staggered in position.

It might be noted here that I use two forms of slabs in the construction of my interior walls, which will be shortly described, as one of the forms of slabs has just been described, the description of the other will now-be pointed out.

Referring to Fig. 6, there is shown a rectangular Slab of plaster '4, which has a binder in the form of a strip of burlap 8 and is also provided'with metal reinforcing rods 9, to add strength. and rigidity to the plaster slab as a who-lei Extending throughout the long dimensions of the slab are the two metal angular members 10 and 11, each of which has a flange 12 cast within the edges of the slab to tightly anchor these metal angles in position. Each of the angle members 10 and 11 are also provided with perforations 13, preferably rectangular in shape, the openings being gored so that tying means may be placed an. where along the metal angles in these staggered openings as will be shortly mentioned.

So far this second slab? is si nihr to the first mentioned slab, but there are additional features about this slab that will now. be mentioned.

Still referring to Fig. 6, it will be seen that at certain spaced intervals, I cut away the slab along the opposite edges as at 14, and I also cutaway the slab at the four corners 15, leaving however the metal angles 10 and 11 at their original length. There are a number of reasons for cutting away the slabs at the points mentioned, The cut away portions 1a provide access openings which are closed by blocks B (see Fig. 1).

In the first place it allows the artisan to procure a convenient grip about the slab when moving it on or oil the wagons or trucks. It

must be remembered that although the slabs are only thick enough for their purpose, any form of plaster slab is heavy and must be handled carefully.

Still another reason for cutting these several openings is to allow the artisan to place his hands through the openings when the s labs are being arranged in their final positior it is necessary to tie one set of slabs to another set when they are arranged as shown in Fig. 1, as will be shortly explained. Also when the slabs are attached to a standing wall as shown in Fig. 201' when they are arranged as shown in Figs. 1* and 8, it is necessary that the slabs be tied to supports or rods.

assay/e openings along the bottom row of slabs, (one block only being shown in Fig. 1), so that the base board may be conveniently secured to these blocks without damaging the plaster slabs. ln the same manner, blocks (not shown) might beplaced in the openings at certain heights, so that a molding may be secured to these blocks atherthan .11 th h the molding and plaster, and blocks can also be placed therein to nail the trim to.

l inally, it may be desired to till the space between the several partitions, or partly fill arranged vertically and adjacent to each,

other. I then take a pluralityof the form of slabs shown in Fig. 6 and arrange these.

horizontally, the outer surfaces of the slabs register-m and the angle membersof the one resting on the angle member of theother. To secure these slabs one tothe other, there is shown the wire strips 16, which will be placed through the staggered openings 1n the respective metal angles of the slabs and then tightly twisted to draw the several parts together. 7

ln l i g. 1 I have only shown three of these wires twistet ,butit will be understood that wherever there is an opening a wire strip will.

be placedthrough the adjacent openings in the angle members to thus tightly pull the various slabs together, or they can behung with open end hooks. It may be desired plaster between the partition and this may be done if so desired,

After the slabs are all in place the openings may be filled with plaster and the adjacent edges of the slabs may be touched up, so

that the entire surfacewillbe flat and in the form of a unitary structure.

As far as the S} )GC lllCttl0Ill1lS now pros ceeded, it will be seen that I do away with the ordinary form of lathing anothe ordinary form of a rough coat and the further smooth coat; the slabs being in their finished form when placed in position.

Referring now for the moment to a slight ly difierent application, I have shown fragmentarily in Fig. 2. a vertical brick wall 17 in which there may be seen the suspension hooks 18 in which there are respectively shown the rods 19. It will be understood that these hooks and rods will extend along to pour Concrete or the brick wallwhile a p'lurality'of the verticalslabs20, which may be of either-f the form shown in Figs. and 6, are then placed against these rods in their vertical position. lllire straps 21 will then be passed around the rods 19 and through the openings 21. in the angle members 22 of the slabs 20, to thus tightly hold the slabs in position.

As may be seen in Fig. 2, an air space will be left between the plaster slabs and the brick wall, which air space is sometimes desirable, although it will be understood should it be desired to fill up this space with plaster or concrete, it may be done, as indicated at A.

Referring now to Fig. 3, there is shown an application of these slabs as used to form a mhanging ceiling. A concrete floor 23 is where either concrete or wooden floors are.

shown, in which there'has previously been cast the sockets 2&. Threaded within these sockets 24; are the hooks 25 in which rests a rod 26. Supported by the rods 26 are the plurality of slabs 2'? which are placed side by side and the wire 28 is passed through the staggered openings 29 of the slabs 27 and about the rods 26 to thus support the ceiling.

The tying is made possible by having the openings so that the wire can be pushed up and threaded through the several openings in the metal members and about the rods 26.

After the ceiling is in position, these small openings in the plaster slabs will be filled with plaster so as to present a smooth surface. It will be noticed that an air space is provided between the slabs and the concrete floor, which will tend to keep the rooms cooler in summer and warmer in winter, it being possible for the air to circulate through the staggered openings of the adjacent metal members. Air space is adjustable to desired width by the screw hook hangers 25, (Fig. 4).

In Fig. 4 I have shown a fragmentary portion of a concrete floor 80 during its forma tion, there being shown the board 31, which is a part of the temporary mold while sockets 2a are placed in position with the temporary bolts 32 inserted in the boardiand socket. After the concrete hardens, the bolts 82 will be removed and the hooks 25 threaded in the sockets which hooks receive the rods 26.

It will be understood that the hooks 25 may be definitely aligned before the rods are placed in position, so that when all the slabs are in position, they will be tightly held in their aligned respective positions.

In Fig. 7 I have shown how the ceiling slabs may be used with the ordinary wooden floors 33 and the joists 34. Strips of wood 35 are nailed across the joists and the slabs 86 are tied as at 37. t will thus be seen that the slabsmay be used to form ceilings used. 7

In Fig. 8 there is shown a slightly different form of wooden floor 38 and a plurality of screw hooks 39, which areused together with 7 From the foregoing paragraphs, it will be seen that I have invented a plaster slab where in a plurality of them may be quickly and readily assembled to form an interior wall of strong and rigid construction. If T desired this wall may be back filled, or in other worcs concrete may be poured between the slabs, so that the slabs in reality form a per manent mold for the fill.

Again I have so constructed the slabs, that not only may they be used to form interior walls, but they may be arranged to form a hanging ceiling.

Walls or ceilings of this nature are desirable as air space is provided, either between the several slabs and a wall or between two adjacent series of slabs;

By cutting out the slabs as heretofore mentioned, it is possible for the plasterers or artisans to easily assemble the slabs and to hang them when desired. Also the pockets allow for wooden blocks to be conveniently inserted, to which base boards or moldings may be secured.

The slabs are ones that may be made in large quantities, easily handled and, inasmuch as they do away with all forms of lathing and labor incident to the old method of plastering, the walls or ceilings may be set up at a relative low cost.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. A plaster slab for walls and ceilings having angular reinforcing members extending along their long dimensions, each of said slabs having cut out portions adjacent the reinforcements and at the four corners of the slabs and wooden blocks placed within certain of said cut away portions.

2. Aplurality of plaster slabs for walls and ceilings, each of said slabs having metal reinforcements along its opposite edges and said slabs also being cut away at their 0pposite corners, a plurality'of rods for holding the slabs in a set position, and means for tying the reinforcements of the plaster slabs to said rods.

3. A plurality of plaster slabs for walls and ceilings, each of said slabs having metal reinforcements along its opposite edges and said slabs also being cut away at their Opposite corners, a plurality of transversely extending means for holding the slabs in their set positions, an adjustable means supporting said first mentioned means and the said slabs tied to said first mentioned means.

i. A wall section comprising a slab of plastic material having access openings at its edges and angle members disposed along the edges ofthe-slab and having flanges embedded in the slab, saidjembeddedflanges being cut away at said access openings.

5. A Wall section comprising a slab of plas 5 tie material having access openings at its edges, angle members disposed along the edges of the slab and having cut away portions registering with the access openings and blocks filling said access openings.

6. A wall comprising a'plura-lity of like slabs, each having angular members at their edges, supporting means adapted to beheld at fixed positions and attaching means forthe slabs acljnstably engaging the supporting means.

In testimony whereof I affix my signature.
